The ghoul is alleged to be the last thing a person sees before they die, often depicted with a scythe and long black hooded gown.

The 48-year-old said: "This is one of the clearest pictures I've taken in my life where I can't explain what the cause is — often you can say someone's breathing into the frame or it's different shades of light playing tricks, but this is something else."

STALKED: Two soldier ghosts can be seen looking at Ethan Harding, 4, from the bushes

6. BLEEDING GHOST SOLDIERS STALK KIDS

Charlotte Harding, 30, visited St Fagans National History Museum in Cardiff last month and to her horror two uniformed ghosts can be seen in the bushes.

She was left unable to sleep after discovering the Battle of St Fagans took place in 1648 in which around 200 soldiers were killed.

Her research also revealed that Parliamentary uniforms looked “just like” what Charlotte caught in her picture.

Charlotte, from Cardiff, said: "The majority of people who have seen the photo think it is two soldiers in Civil War uniforms, like two men talking together. I can see it too.”
